Description

Technical Field

[0001] This solution belongs to the field of textile equipment technology, specifically involving a yarn clamp cleaning device. Background Technology

[0002] Yarn clamps are key components in spinning equipment used to hold and control the movement of yarn. Their function is to ensure spinning quality and efficiency by stabilizing yarn tension. For example, in equipment such as ring spinning frames and air-jet looms, yarn clamps need to precisely hold the yarn to ensure that the yarn maintains uniform tension during twisting, winding, or weaving, avoiding problems such as yarn breakage, slack, or tension fluctuations.

[0003] During the spinning process, yarn clamps easily accumulate impurities such as cotton dust and fiber debris due to yarn friction. Traditional cleaning methods (such as compressed air blowing) can only remove surface impurities and cannot penetrate deep into the yarn. Over time, these accumulated impurities can jam the clamping components, causing the yarn clamp to become stuck or jammed when dropping yarn or changing tubes, interrupting the production process, increasing friction and wear between components, and shortening its service life.

[0004] See the existing publication (announcement) number CN202047202U, which discloses a cleaning impeller device for a weft yarn clamp on a loom. This device includes an impeller and multiple blades. The impeller is directly mounted on the shaft head of the loom main shaft, and the multiple blades have at least two different installation angles. This device achieves cleaning by blowing away fly lint and down around the clamp. Furthermore, the existing publication (announcement) number CN220887901U discloses a roller-type clamp for a circular knitting machine, including a fixed plate and a cleaning component for removing impurities from the outer surface of the yarn. The cleaning component includes a support frame fixedly connected to one side of the bottom of the fixed plate, a guide roller connected to the lower part of the support frame, and a cleaning roller located in the upper part of the support frame. This clamp pre-removes impurities such as lint from the outer surface of the yarn by using the cleaning roller, ensuring the cleanliness of the yarn and reducing dust around the clamp.

[0005] Although the above-mentioned devices clean the yarn clamp and yarn surface by means of blade blowing and cleaning roller respectively, which can reduce cotton dust around the yarn clamp to a certain extent, it does not mean that there is no cotton dust around the yarn clamp, and it cannot clean the inside of the yarn clamp. The cotton dust and impurities accumulated inside the yarn clamp will cause problems such as jamming and wear of the yarn clamp. Utility Model Content

[0006] The purpose of this solution is to provide a yarn clamp cleaning device to solve the problem of cleaning the inside of the yarn clamp.

[0007] To achieve the above objectives, this solution provides a yarn clamp cleaning device, including a first cleaning component, the first cleaning component comprising: A fixed sleeve, wherein the fixed sleeve is connected to a high-pressure air source via a pipe; A movable sleeve, one end of which is connected to a fixed sleeve, wherein the outer diameter of the movable sleeve is smaller than the inner diameter of the yarn clamping core, so as to be inserted into the yarn clamping core; The nozzle penetrates the side wall of the movable sleeve and communicates with the inner cavity of the movable sleeve. The nozzle is used to guide the gas provided by the high-pressure gas source into the interior of the yarn clamping core.

[0008] The principle and effect of this solution are as follows: A fixed sleeve connects to a high-pressure air source to provide power. The movable sleeve, with an outer diameter smaller than the inner diameter of the yarn clamp's core, can be inserted inside. The nozzles penetrating the side wall of the movable sleeve guide the high-pressure gas into the core. When the high-pressure airflow exits through the nozzles, it forms an impact airflow that sweeps the inner wall of the yarn clamp's core, blowing out accumulated cotton dust, fiber debris, and other impurities. This prevents parts from jamming or seizing due to impurity accumulation, while also reducing component wear and extending the yarn clamp's service life.

[0009] Furthermore, the outer diameter of the fixed sleeve is larger than the inner diameter of the yarn clamp core; the number of spray holes is multiple, and they are spaced apart circumferentially along the center of the movable sleeve.

[0010] The principle and effect of this solution are as follows: the outer diameter of the fixed sleeve is larger than the inner diameter of the yarn clamp core, allowing it to contact one end of the core, preventing high-pressure gas from being ejected from that end. This forces the gas to carry impurities only through the other end of the core for discharge. Multiple circumferentially spaced nozzles allow high-pressure airflow to impact the inner wall of the core from different positions, forming a surrounding airflow that sweeps cotton dust and impurities from inside the core to the other end for discharge.

[0011] Furthermore, the outer wall of the movable sleeve is slidably connected to the inner wall of the fixed sleeve, and the height of the movable sleeve is not less than the height of the yarn clamp core.

[0012] The principle and effect of this solution are as follows: by gradually increasing or decreasing the airflow rate of the high-pressure gas source, the air pressure inside the movable sleeve increases or decreases. The airflow pushes the nozzle to eject gas, generating axial thrust that drives the movable sleeve to slide along the inner wall of the fixed sleeve. Because the movable sleeve completely covers the core, its movement causes the nozzle to reciprocate axially along the core, resulting in better cleaning of the core.

[0013] Furthermore, the axis of the nozzle is inclined at an angle α relative to the axis of the movable sleeve, and the angle α is 15°-20°, so that the airflow ejected from the nozzle is inclined toward the inner wall of the yarn clamping core.

[0014] The principle and effect of this solution are as follows: When the gas ejected from the nozzle is horizontal, the airflow direction is perpendicular to the inner wall of the yarn clamping device core, making it easy to blow impurities to press tightly against the inner wall of the core, creating a "the more you blow, the tighter it gets" cleaning dead zone, rather than blowing them out. Therefore, by setting the nozzle to be tilted at 15°-20° along the axis, the airflow acts on the inner wall of the core at an oblique angle, reducing cleaning dead zones and achieving a better cleaning effect.

[0015] Furthermore, it also includes a second cleaning component, which includes a drive shaft and fan blades. One end of the drive shaft is connected to a support rod, and the free end of the support rod is rotatably connected to the inner wall of the fixed sleeve. The free end of the drive shaft passes through the top wall of the movable sleeve. The fan blades are coaxially connected to the drive shaft and are disposed in the inner cavity of the movable sleeve. The blades of the fan blades are evenly distributed around the circumference of the drive shaft and are spirally twisted. The spiral angle of the blades is adapted to the α angle, which is used to eject the high-pressure airflow from the nozzle at the α angle.

[0016] The principle and effect of this scheme are as follows: when the high-pressure airflow enters the inner cavity of the movable sleeve, the blade helical angle is matched with the nozzle tilt angle α (15°-20°). After the airflow is guided by the fan blade, it forms a pre-rotation angle consistent with the nozzle axis, so that the airflow is ejected from the nozzle at an angle.

[0017] Furthermore, the rotating shaft of the fan blade is fixedly connected to the top wall of the movable sleeve; a guide groove is provided on the outer wall of the drive shaft, and the rotating shaft of the fan blade is slidably connected to the guide groove.

[0018] The principle and effect of this solution are as follows: when the high-pressure airflow drives the fan blade to rotate, since the rotating shaft is fixed to the movable sleeve, the fan blade drives the movable sleeve to rotate synchronously in the circumferential direction; at the same time, the guide groove causes the fan blade rotating shaft to move along the length direction of the drive shaft, thereby driving the movable sleeve to slide back and forth along the axial direction of the yarn clamp core, so that while the nozzle sprays out the inclined airflow, it also performs a spiral sweep along the core wall, resulting in a better cleaning effect on the inside of the yarn clamp.

[0019] Furthermore, the drive shaft has a hollow structure, and one end of the drive shaft located inside the fixed sleeve has an opening that communicates with the cavity; the side wall of the drive shaft has a through-hole that communicates with the cavity, and the axis of the through-hole is parallel to the top surface of the yarn clamping core, so that the gas ejected from the through-hole forms a horizontal airflow that covers the top surface of the yarn clamping core.

[0020] The principle and effect of this scheme are as follows: (1) This device is generally installed on a machine tool, and there are multiple devices. In order to facilitate the installation of the yarn clamp on the cleaning device, the fixed sleeve is generally set vertically. When multiple cleaning devices are running at the same time, the blown cotton dust and fiber debris will float in the air for a period of time. When the nozzle sprays air to clean the yarn clamp, since the nozzle rotates circumferentially, the air flow is generally smaller in the middle of the yarn clamp, so that the impurities floating in the air fall into the yarn clamp from the middle position. (2) In this scheme, since one end of the drive shaft is open and connected to the cavity and the air hole, when the airflow drives the fan blade to rotate and drives the drive shaft to rotate, part of the airflow will enter the cavity from the opening and finally be sprayed out from the air hole. Since the drive shaft is rotating circumferentially, it will drive the air hole to rotate synchronously, so that the gas sprayed out of the air hole will form a ring-shaped air curtain, thereby blocking and covering the top surface of the bobbin to prevent the impurities floating above from entering the yarn clamp.

[0021] Furthermore, the diameter of the opening is smaller than the inner diameter of the movable sleeve, so that the intensity of the airflow ejected through the air hole is less than the intensity of the airflow ejected through the nozzle.

[0022] The principle and effect of this solution are as follows: the reduction in the opening diameter leads to a decrease in the airflow entering the drive shaft cavity, which makes the airflow intensity of the air hole lower than that of the main airflow of the nozzle. This allows the air curtain to form a barrier on the top surface of the yarn clamp core, blocking airborne impurities from falling, without closing the top opening of the core due to excessive airflow, so that the main airflow of the nozzle can discharge the cleaned impurities from the top of the core.

[0023] Furthermore, the vent is provided with a sealing ball for sealing the vent, and the sealing ball is connected to a spring, the free end of which is fixedly connected to the vent.

[0024] The principle and effect of this solution are as follows: the sealing ball and the spring act as a one-way valve. Only when there is gas in the drive shaft and the drive shaft is rotating, the sealing ball will be stretched by the thrust of the gas and the centrifugal force of the rotation, which will cause the air hole to open and generate the air jet gap.

[0025] Furthermore, the fixed sleeve is connected to a regulating valve via a pipe, and the air inlet of the regulating valve is connected to an air compressor.

[0026] The principle and effect of this solution are as follows: by adjusting the flow rate of the high-pressure air source through the regulating valve, the circumferential movement of the movable sleeve within the yarn clamp is controlled. When the opening of the regulating valve increases, the air flow rate increases, the air pressure inside the movable sleeve rises, and the resulting axial thrust drives the movable sleeve to slide upward along the inner wall of the fixed sleeve; conversely, when the opening of the regulating valve decreases, the flow rate decreases, the air pressure decreases, and the movable sleeve slides downward under the action of gravity or the reset mechanism, thereby causing the nozzle to reciprocate along the axial direction of the yarn core for cleaning.

Detailed Implementation

[0029] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Example: Please see Figures 1-3 This embodiment provides a yarn clamp cleaning device, comprising a first cleaning component 1 and a second cleaning component 2, suitable for cleaning the inside of the yarn clamp 3 core in textile equipment. This device is vertically mounted on a machine tool 4, with several units arranged to facilitate simultaneous cleaning of multiple yarn clamps 3. The yarn clamp 3 is an existing device; see the yarn clamp structure in patent document CN116752255A.

[0030] Please see Figure 1 and Figure 3The first cleaning component 1 includes a fixed sleeve 11, a movable sleeve 12, and a spray nozzle 13. One end of the fixed sleeve 11 is provided with a gas interface, which is connected to an air compressor (not shown) through a pipe. A regulating valve 14 for adjusting the airflow is provided on the pipe. The regulating valve 14 controls the air pressure inside the movable sleeve 12 by adjusting the airflow. Both the fixed sleeve 11 and the movable sleeve 12 are cylindrical. The outer diameter of the fixed sleeve 12 is larger than the inner diameter of the yarn clamp 3 core, and it abuts against one end of the core to form a sealing structure to prevent high-pressure gas leakage. One end of the movable sleeve 12 is located inside the fixed sleeve 12, and the other end of the movable sleeve 12 is connected to the fixed sleeve 11. A rubber ring is provided at one end of the movable sleeve 12. The movable sleeve 12 can move up and down and rotate circumferentially inside the fixed sleeve 12. The outer diameter of the movable sleeve 12 is smaller than the inner diameter of the bobbin, and it can be inserted into the bobbin of the yarn clamp 3. Multiple spray holes 13 are evenly distributed around the top side wall of the fixed sleeve 12. The axis of the spray holes 13 is inclined at 15°-20° relative to the axis of the movable sleeve 12, and the inner diameter is 0.5-2mm. This allows the high-pressure airflow to impact the inner wall of the bobbin at an oblique angle, avoiding the problem of traditional vertical airflow "pressing" impurities onto the wall surface and improving the impurity cleaning efficiency.

[0031] Please see Figure 4 and Figure 5 The second cleaning component 2 includes a drive shaft 21 and a fan blade 22. One end of the drive shaft 21 is connected to a support rod 23. The free end of the support rod 23 is rotatably connected to the inner wall of the fixed sleeve 11. The inner wall of the fixed sleeve 11 is provided with an annular groove structure (not shown), allowing the free end of the support rod 23 to slide within the groove and achieve circumferential rotation. The free end of the drive shaft 21 passes through the top wall of the movable sleeve 12. A guide groove 211 is provided on the outer wall of the drive shaft 21. The guide groove 211 is arranged along the length direction of the drive shaft 21. The rotating shaft of the fan blade 22 is slidably connected to the guide groove 211, and the rotating shaft of the fan blade 22 is fixedly connected to the top wall of the movable sleeve 12 (e.g., ...). Figure 4 As shown, the fan blade 22 can drive the drive shaft 21 and the movable sleeve 12 to rotate, and can also slide up and down along the length of the drive shaft 21. When the high-pressure airflow pushes the fan blade 22 to rotate, the guide groove 211 causes the fan blade 22 to drive the movable sleeve 12 to rotate circumferentially and move axially, so that the nozzle 13 forms a spiral sweeping trajectory, expanding the cleaning coverage area. The fan blade 22 is coaxially connected to the drive shaft 21 and is located in the inner cavity of the movable sleeve 12. The blades of the fan blade 22 are evenly distributed along the circumference of the drive shaft 21 and are spirally twisted. The spiral angle of the blades is matched with the α angle, which is used to spray the high-pressure airflow out from the nozzle 13 at the α angle.

[0032] Please see Figure 6 and Figure 7The drive shaft 21 has a hollow structure, and one end of the drive shaft 21 located inside the fixed sleeve 11 has an opening that communicates with the cavity. A vent 212 penetrates the side wall of the drive shaft 21, communicating with the cavity. The axis of the vent 212 is parallel to the top surface of the yarn clamp 3 core, allowing the gas ejected from the vent 212 to form a horizontal airflow covering the top surface of the yarn clamp 3 core. The vent 212 is equipped with a sealing ball 24 for sealing the vent 212. The sealing ball 24 is connected to a spring 241, and the free end of the spring 241 is fixedly connected to the vent 212. The sealing ball 24 and the spring 241 function as a one-way valve. Only when there is gas inside the drive shaft 21 and the drive shaft 21 is rotating, the sealing ball 24 is subjected to the thrust of the gas and the centrifugal force of the rotation, which stretches the spring 241 to open the vent 212, creating an air gap (such as...). Figure 6 (As shown). It should be noted that the diameter of the opening is smaller than the inner diameter of the movable sleeve 12, so that the airflow intensity ejected through the air hole 212 is less than the airflow intensity ejected through the nozzle 13. This ensures that although the air curtain can form a barrier on the top surface of the yarn clamp 3 bobbin to prevent airborne impurities from falling, it will not close the top opening of the bobbin due to excessive airflow, allowing the main airflow of the nozzle 13 to discharge the cleaned impurities from the top of the bobbin.

[0033] During operation, the high-pressure airflow from the air compressor enters the fixed sleeve 11 via the regulating valve 14. Due to the sealed design between the fixed sleeve 11 and one end of the core, the airflow is obliquely ejected from the nozzle 13 of the movable sleeve 12, impacting the inner wall of the core and removing impurities. The regulating valve 14 adjusts the flow rate, driving the movable sleeve 12 to reciprocate and expand the cleaning range. The fan blades 22 guide the airflow to form a pre-rotation angle, enhancing the cleaning ability of the airflow from the nozzle 13, while simultaneously driving the movable sleeve 12 to rotate circumferentially, causing the nozzle 13 to rotate synchronously, achieving 360° cleaning. At the same time, some airflow is ejected from the air hole 212 through the cavity of the drive shaft 21, forming an air curtain to prevent floating impurities from falling into the yarn clamp 3. After this device was put into use, the daily damage to the yarn clamp 3 was reduced by 10%, improving the cleaning efficiency and operational stability of the yarn clamp 3 in large-scale textile production.

[0034] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
